Scraper knife capable of removing rubbish back and forth
The invention discloses a scraper knife capable of removing rubbish back and forth, and aims to provide a scraper knife capable of removing rubbish back and forth, improving working efficiency and removing different attachments well and convenient to operate. The scraper knife comprises a knife blade, a knife handle and a handle sleeve. An upper knife blade is arranged on the upper portion of the knife blade, a hook-shaped knife edge is arranged at one end of the upper knife blade, and the included angle between the hook-shaped knife edge and the upper knife blade is 30 degrees. A lower knife blade is arranged on the lower portion of the knife blade, a hook-shaped knife edge is arranged at one end of the lower knife blade, and the included angle between the hook-shaped knife edge and the lower knife blade is 45 degrees. The knife handle is located in the axial direction of the handle sleeve and provided with a knife blade groove of which the section is of a rectangular structure. The tail of the upper knife blade, the tail of the knife blade and the tail of the lower knife blade are overlapped to be matched with the knife blade groove. When the hand pushes the scraper knife forwards, the knife blade is used for clearing away attachments on the working face; when the hand pulls the scraper knife back, the upper knife blade or the lower knife blade is used for clearing away the attachments, and therefore working efficiency is improved greatly.
